Abstract.
Designs of dielectric dome lens antennas are presented, areas of their
application are defined. The numerical research of the aerodynamic and
energy parameters of the dome lens antennas on the aircraft is carried
out. The dependencies of the aerodynamic drag coefficient and antenna
gain for the geometric dimensions of the lens of the antenna on the
aircraft, which accomplishes flight at the height of 8 km above sea
level at a rate of 400km/h are obtained. The possibility of reduction in
the aerodynamic drag coefficient of antenna by decreasing the geometric
dimensions of dome lens with the retention of the value of the antenna
gain is shown. The numerical research of the antenna gain and factor of
safety for max von Mises criterion is carried out. The possibility of
increasing more than 2 times the factor of safety by changing geometric
parameters of the lens in the range of 20% on the baseline values, and
also their rational selection with the value retention of the required
antenna gain is shown.
